[ros-dev] atapi problems

[Ge van Geldorp]

I'm having problems getting atapi drives recognized. Setup:

Primary controller
- master: HD HITACHI_DK23AA-60
- slave: CD-ROM COMPAQ CD-224E

Secondary controller
- master: not connected
- slave: not connected

First of all, the harddisk is not recognized. The call to
AtapiWaitForStatus() in atapi.c line 1159 times out. I can fix this by
increasing the timeout in that call from 20000 to 40000 (the harddisk needs
a minimum of around 38700 here).

After the harddisk is succesfully recognized, detection of the CD-ROM fails.
Again, the call to AtapiWaitForStatus in line 1159 times out, but this time
no amount of increasing the timeout (I've gone up to 4000000, 40 sec, more
than the 30 sec limit in the ATA spec) helps. I've attached the debug log.
Note the lines:

(atapi.c:1161) Timeout on drive 1
and
(atapi.c:992) Unexpected Interrupt, CommandPort=01f0, Status=ff, Count=1

I hope someone more familiar with the atapi driver can take a look at this.
Oh, btw, going back to atapi.c rev 48 cures the problem (both HD and CD-ROM
are recognized and working then).

All help appreciated, Gé van Geldorp.
